The research was done at the Experimental animal hospital of the Faculty of Veterinary Medicineof the Latvia University of Agriculture. Four experimental groups were arranged, five animals in each: twogroups of adult goats at the age of 1-2 years and two groups of kids, 2-3 months old. All goats were operatedfor insertion of chronic rumenal and abomasal fistulae. Additionally, digestive strongylida larvae were culturedfor artificial infection of goats. Each animal of one adult goat group and one kid group was infected via rumenalfistula with 5000 O. circumcincta L 3larvae, but the other animals – with 10 000 O. circumcincta L 3larvae.To estimate the level of invasion, examination of faeces was made starting from day three every day afterstrongylida larvae infection. Blood samples in goats were taken five times before the invasion and five timesin the third and fourth week after invasion. Changes in blood haematological parameters were observed ingoats that received O. circumcincta L 3larvae: the count of eosinophil leucocytes significantly increased from1.63-3.00% to 12.20%-14.00% (p
